Patho-Physio 3

adhesive spots on lateral sides linked by proteins/filaments, holds tissues together

at apical area, plasma membrane of adjacent cells fuse, nothing passes

spot-like junction occurring anywhere made of hollow cylinders of protein, lets small molecules pass

-ductless glands

-secrete product (hormones) directly into blood stream

secrete matrix in cartilage

secrete matrix in bone

make protein subunits of fibers, secrete ground substance

store energy

neutrophils, lymphocytes, macrophages- fight infection

signal inflammatory response; promote healing

derived from blood in CT proper; medium for nutrients, waste + oxygen to travel to cells; found in ground matrix

gelatinous material found between cells; protects by absorbing compressive forces

-unusual disaccharides that attract sodium & hold water

-important role in regulating water & electrolyte balance

embedded in plasma membranes; crates a strong bond to other cells or extracellular macromolecules

protein-carbohydrate complexes that bind plasma membrane to collagen or proteoglycans outside the cells.

production of blood cells; occurs in red bone marrow

(RBC) small, oxygen-transporting

-most abundant cell type in blood

-few organelles or nuclei

-hemoglobin-binds O2 at lungs, transports to body

-cell fragments from karyocytes

-initiates clotting process

- 5 different classes; characterized by staining and nuclear characteristics

-fight against infections

-bone marrow derived

-long and cylindrical, in bundles

-multinucleated

-obvious striations

-branching, chains of cells

-single or binucleated

-striations

-connected by intercalated discs

-singled cells, uninucleated

-no striations

specialized nerve cells conduct impulses composed of cell body, dendrite, axon

nonconducting cells that nourish, insulate, and protect neurons

surround cell bodies within ganglia

surround axons

phagocytes

produce myelin sheaths

line brain/ spinal cord, ciliated, help circulated CSF
